There is a Charter monitor but for large ISPs dividing it up into regions makes more sense (much like what the Road Runner group did). Information about the Charter group is here: »Charter Internet Line Monitoring - It's free

You might ask skj to make regional divisions for Charter monitors. If there's enough interest I'm sure he'd do so.

You're welcome to monitor as part of the SoCal region in addition to the Charter group. Your one monitor can be shown in both groups.

Seagreen,Thanks for the invite ...but...what can I say,... I'm a klutz, or perhaps it was the margarita I had for lunch... while updating my IP address, I managed to disengage myself from monitoring...could you reinvite me please?
